GAS-REGULATOR.

This invention relates to a gas regulating device, designed to automatically reduce, or if desired, to entirely out off the flow of gas to a burner upon the removal of a vessel therefrom, and also to automatically start or increase flow of gas to said burner when the vessel is replaced.

With these objects in view the invention consists of the novel features of construction hereinafter described, pointed out in the claims and shown in the accompanying drawings, in which:

Figure 1 is a sectional side elevation of the device. Fig. 2 is a section on the line 2-:2 of Fig. 1.

In these drawings 1 represents a burner 1 and 2 a gas supply pipe to said burner. 1n the horizontal portion of said pipe is ar ranged a valve seat 3 adapted to be closed by means of a vertically movable valve 4:. A short vertically arranged branch pipe 5 communicates with the pipe 2 in alinement with said valve seat and said pipe supports a cylindrical vessel 6, the top and bottom of which is formed of some suitable flexible resilientmetal." The said vessel carries a stufling box 7 arranged centrally upon the top of the receptacle and a valve stem 8 is connected at its lower end to the valve 4 and extends upwardly through the pipe 5 centrally and transversely through thereceptacle 6 and through the stuffing box 7, the said stuffing box fitting tightly upon said stem. Pivotally mounted upon the upper end of the valve stem is a lever 9, one end of which works in the upper slotted portion 10 of a bracket 11, and the other end works in a slot 12 formed in a sleeve 12, which sleeve is supported from the vertical portion of the pipe 2. A suitable rod 18 pro jects upwardly through the burner 1 and at its lower end is pivotally connected to the lever 9 within the sleeve 12. A suitable adjusting screw 14 works through the top of the bracket 11 and bears upon the upper edge of the lever 9.

The screw 14 can be set so that the pressure of gas within the vessel 6 will cause the Specification of Letters Patent. patentgd Bag, 29, 19.14 Application filed May 2, 1914. Serial na-sssesa valve to seat itself, asshown in Fig. 1,

thereby completely cutting off the flow of gas to "the burner. that if it is desired to retain a low flame in the burner when not "in use the adjusting But 'it will be obvious screw 14: can be turned down so as to limit upward movement of the lever 9 thereby preventing vertical movement of the stem 8 and the valve 4 to completely out off the flow of gas. As soon as a vessel is placed upon the burner 1 the weight of the vessel will force the rod 18 downwardly, thereby forcing down the stem 8, as shown in dotted lines and also forcing inwardly the top and bottom and especially the top of the vessel 6. This of course moves the valve l into the position shown in dotted lines thereby permitting the free flow of gas to the burner.

It willbe noted therefore that either the pressure of the gas of itself or the gas pressure combined with the resilience of the top and sides of the vessel, when such material is employed, perform automatically those functions which have heretofore been performed by the mechanical turning of the valve stem either by hand or by directly connecting said valve stem to some movable part provided with springs or counter weights.

An adjusting screw 15 works through the lever 9 and regulates the downward movement of the valve 4 so that the size of the flame can be regulated, the screw 15 bearing at its lower endupon a shoulder 16 formed on the bracket 11. The screw 14 by'bearing upon the top of the lever 9 will regulate the amount of proiection of the rod'13 through the burner, thereby regulating downward movement of said rod. the le er 9 and the stem 8, this movement being limited by the screw 15. By means of these two screws perfect adjustmentmay be had of all parts.

What I claim is 1. The combination with a gas supply pipe, of a vessel having a flexible top and bottom portion and having free communication with said pipe, a valve in said pipe, a stem for said valve, the stem passing through said vessel, means for securing the horizontally arranged vessel having free communication with said pipe in advance of said valve, said vessel being normally expanded by pressure of gas, a valve stem passing through said vessel, means for connecting said stem With the top of the vessel, and

meaans for connecting said stem with said ro Y 3. In a device of the kind described comprising a gas supply pipe, a valve therein adapted to regulate passage of gas through said pipe, a branch pipe in alinement with said valve, a cylindrical vessel mounted upon said pipe, said vessel having flexible sides and being in communication through said said burner.
